Which radars cover Arapahoe?
The closest NEXRAD Doppler radar is KRIW (Riverton, WY), about 5 miles north-northwest. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Arapahoe | View |
|---|---|---|---|
| KRIW Riverton, WY | 5 mi north-northwest | 300 ft | Excellent — the lowest scan sees close to the ground |
| KBLX Billings, MT | 198 mi north | 28,700 ft | Limited — the beam overshoots the lowest part of storms |
| KSFX Pocatello, ID | 214 mi west | 32,700 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
